Description
Technical field
The present invention relates to a kind of actuating unit, more particularly to a kind of machinery-electric power for engineering machinery is passed
Dynamic device.
Background technology
Engineering machinery often uses hydraulic drive or hydraulic power, is engaged with machine driving, constitutes hybrid power transmission
Device, to realize the high-power transmission under complex working condition, and causes that transmission system has certain flexibility.In recent years, develop
Machine liquid Composite Transmission mode, while requirements above is met, high-efficiency infinite variable speed is realized well.But in control accuracy
It is also to be further improved with energy-saving and emission-reduction aspect.
Obviously, gear is fewer, is more easily controlled.Hydraulic machinery variable speed has two kinds of whole formula and segmented.Whole formula
Hydraulic pressure (fluid power) mechanical transmission gear is less, but quite high to hydraulic part requirement, is all difficult in technology and economic aspect；Point
Segmentation hydraulic pressure (fluid power) mechanical transmission is reduced to hydraulic part requirement, but causes gear showed increased, and each gear often needs control
Multiple clutches and brake apparatus, it is difficult to realize optimal control.
The parallel systems that mechanically and electrically two kinds of kinds of drive of power are constituted, as an important think of for solving this technical barrier
Road.The intelligent Matching of engine-transmission-walking (work) system can not only preferably be realized, moreover it is possible to realize from higher level
The integration of people-machine-environment.
The content of the invention
Goal of the invention：It is an object of the invention to provide a kind of machinery-electric power transmission device, human hair can be preferably realized
The matching of motivation-actuating unit-walking (work) device, and then realize the integration of people-machine-environment.
Technical scheme：A kind of machinery-electric power transmission device, including input shaft, machine driving input gear pair, electric power
Drive assembly, planetary gear gearshift assembly, power output assembly and output shaft, the Electric Drive assembly include that Electric Drive is defeated
Enter gear pair, electric drive and Electric Drive output gear wheel set；The planetary gear gearshift assembly includes high tap position clutch
Device, gear clutch, low-regime clutch, gear ring, planet carrier, sun gear and sun wheel shaft；The power output assembly bag
Include power output gear pair and equipment transfer tube.
Principle：
When high-regime clutch is engaged, the power of engine output is divided into two-way, all the way through machine driving input gear
Pair is delivered to planet carrier, is delivered to sun gear through Electric Drive assembly all the way, and hybrid power is exported through gear ring from output shaft, this
That is high tap position.
When the when of falling gear clutch is engaged, planet carrier is fixed, and the power of engine output is passed through Electric Drive assembly
Sun gear is delivered to, through gear ring, from output shaft output, this is reverse gear position.
When low-regime clutch is engaged, the planetary gear in planetary gear gearshift assembly holds together admittedly, starts
The power of machine output is delivered to sun gear through Electric Drive assembly, is finally exported from output shaft, and this is low-grade location.
Preference, actuating unit simple structure is easy to operate, only manipulates a clutch, you can realize correspondence shelves
The change of position.
Preference, electric drive on startup, releases energy, used as the auxiliary power source of engine；During braking, will
Mechanical energy is converted into electric energy, stores；The energy of super capacitor storage can also drive work clothes in addition to it can drive running gear
Put, and energy stores unnecessary in the assembly that can output power are in super capacitor.
Preference, controller collects the signal of engine, actuating unit, running gear and equipment, and sends
Control instruction, realizes Optimized Matching, finally realizes people-machine-environmental integration.
Beneficial effect：1. the actuating unit only needs to control three clutches on planetary gear gearshift assembly, you can
Realize the switching of high tap position, reverse gear position and low-grade location；2. Electric Drive not only causes that control is more accurate, but also with system
Energy reserve, the advantage released energy during startup when dynamic；3. the energy of super capacitor deposit can also drive power output assembly
Equipment transfer tube；4. the power transmission system structure is simple, easy to operate, and control is accurate, preferably realize engine-
The matching of actuating unit-walking (work) device.
Brief description of the drawings
Fig. 1 is machinery-electric power transmission structures figure；
Fig. 2 is each gear clutch switch operating schematic diagram of actuating unit.
Specific embodiment
Technical scheme is described further with instantiation below in conjunction with the accompanying drawings.
When high-regime clutch 5-1 is engaged, the power of engine output is divided into two-way, is input into tooth through machine driving all the way
Wheel set 1 is delivered to planet carrier 5-5, is delivered to sun gear 5-6 through Electric Drive assembly 3 all the way, hybrid power through gear ring 5-4, from
Output shaft is exported, and this is high tap position.
When the 5-2 of falling gear clutch is engaged, planet carrier 5-5 is fixed, and the power of engine output is through Electric Drive
Assembly 3 is delivered to sun gear 5-6, and through gear ring 5-4, from output shaft output, this is reverse gear position.
When low-regime clutch 5-3 is engaged, the planetary gear in planetary gear gearshift assembly 5 holds together admittedly,
The power of engine output is delivered to sun gear 5-6 through Electric Drive assembly 3, is finally exported from output shaft, and this is low-grade location.
